Yup, on first bootup, the xserver failed to start.  It took a couple
of attempts at playing with the xorg.conf, but luckily all graphics
drivers are installed by default, so I just had to specify "810" as
the driver and it was soon back up and running.

I also commented out a couple of drivers like "GLCore" and "glx" but
as I haven't tried to get the 3D acceleration working yet, I am not
sure if I need them or not.  I will work all that out tonight.

I also changed to the 686 kernel, which has SMP all enabled now so
after a reboot I could see both cores and they seem to be utilised
correctly.  I have to admit, I am was mighty impressed with how easy
it all was.

I have an Edgy live CD somewhere, so I will probably do this anyway to
check I have my xorg.conf file configured right.

I also don't seem to have any sound.  Everything seems to be
recognised correctly as an Intel ICH5 onboard 6 channel thingo so I am
just praying it is not a hardware issue.  I am hoping that by using
the Edgy live CD I can at least confirm the sound is working fine.

Thanks for the responses,
